Fiber optics is primarily utilized in environments with high electromagnetic interference (EMI) due to its inherent EMI resistance properties. Unlike copper cables, which can easily be affected by electromagnetic fields and can pick up noise, fiber optic cables transmit data as light through a glass or plastic medium. This makes them immune to EMI, ensuring that the signals remain clear and unaffected by external electromagnetic disturbances.

In settings such as industrial plants, hospitals, or areas near heavy machinery, the ability to maintain signal integrity in the presence of significant EMI is crucial for communication and data transmission. Other factors, such as safety or size reduction, may have their own considerations in different contexts, but EMI resistance is the primary reason fiber optics is the preferred choice in such environments. Cost-effectiveness might also play a role in fiber optic deployment, but it does not directly address the issue of EMI.
